Application filed December 21, 1927. Serial No; 241,480.

This invention relates to looms and particularly to looms for Weaving wire cloth for use in paper making machinery.

An object of this invention is a loom by means of which wire cloth of different weaves may be produced without. rethreading the loom.

According to this invention, the loom is equipped with a plurality of heddles prefer harness is connected to theend of a support ing band passed over a pulley or the like so that the harnesses'fare caused to niove in unison. When the loom is used to produce wire cloth of standard weave, each harness is supported by a single band. However, when the loom is used to produce wire cloth havin twilled weave or modifications thereof, eac

' harness is supported by atleast two bands,

the number of bands-being" refer-ably" equal to the number of'h'eddles. y changing the connections between the -harnesses andthe operating members and between the harnesses and the supporting bands and the connections between theoperating. and'the actuating members, the'l-oom may be usedto produce, without rethreading wire cloth having different weaves. e V

Figure 8 is a portion of astrip of wire cloth showing different weaves produced by the harness'arrangements in Figs. 4-.to 7 inclusive. Figures 9' to 19 inclusive are sections on the correspondinglynumbered lines in Fig. 8. In Figs. 1 and .2, 10 is the frame of the loom, 1-1 is the back beam, 12 is the breast beam, 13 is the cloth roll, 14 is the shuttle carrier515 is the shuttle. and 16 is the lay beam. These elements. form no part of the instant invention and for this reason the operatingmeans therefor are notshown.

17 designates the harnesses which in the present embodiment of the invention are six in number although a greater number may be used if desired. The harnesses are supported by means of bands 18 which pass over pulleys or the like 19 supported by the frame 10.

One end of eachband is connected'to one harness so that the harnesses are mounted for movement in unison. Rollersor pulleys 20 are supported by the framefand chains or cords 21 connect each heddle with one of the rollers 20. Rotation of any one-of the pulleys 20 will cause two or more ofthe harnesses to be pulled downwardly,the remaining harnesses being pulled upwardly by means of the bands 18.

In some instances, two rollers are used, in which case half" of the harnesses are connected to one; roller" and half to the other. (see Fig. 2 When so connected, only three bands 18 are used, one end of each band beingconnected to one of the harness of a set of three andthe other end ofjthe band being connected to one harness of the other set of,

and is provided with a'roller.24 which engages a am 2 m unt d-0n the countemheft 26. The cams are so designed and arranged that there is always one roller 24 out of contact with its cam. The cam shaft 26 is driven by means of a main shaft 27 suitably geared to the countershaft 26. Each lever 22 is of such weight that, when its roller 24: is disengaged from its coacting cam 25, it drops down, thereby causing rotation of the correspondlng roller 20 and eifecting movement of the harnesses connected thereto. When two rollers 20 are used, each of the cams has a circular surface of approximately 180 of arc (Fi 2), and when three rollers are used eac cam has a circular operating surface of approximately 240 of arc (Fi 2). In the latter case each cam is engage with a roller 24 during two-thirds of a revolution of the shaft 26, the arrangement of the rollers being such that the opposite ends of two of the levers 22 are elevated at any time while the corresponding end of the third operating lever 22 is depressed when 180 cams are used the ends of the operating lever are alternately elevated and depressed.

The warp wires A lead from the back beam 11 through the usual eyes in the harnesses 17, through the lay bar 16, over the breast beam 12 and to the cloth roll 13. The successive warp wires pass respectively through the harnesses in the following order, 17 17, 17, 17 17, 17 (see Fig. 3) and repetitions thereof. The harnesses 17 may be of any type suitable to the wire used and the conditions present in the loom.

In Figs. 1 and 2 the loom is shown as being equipped with three rollers 20, six harnesses 17 and six supporting bands 18. Each harness has connected thereto the ends of two supporting bands and the harnesses are connected in pairs to the rollers 20 by the cables 21. The loom is also provided with three actuating levers 22 and three 240 actuating cams 25. By diflFerently arranging the connections between the supporting bands, harnesses and rollers the second, third and fourth weaves illustrated in Fig. 8 may be produced. The necessary connections and the sequence of movement of the harnesses for producing these weaves are diagrammatically disclosed in Figs. 5 to 7 inclusive. Bv usinn only two rollers 20 and three supporting bands 18, the ordinary weave or the first weave dis closed .in Fig. 8 may be produced. Fig. 4 illustrates the connections and the sequence of movements for producing this weave while Fig. 2 shows the arrangement of cams and actuating members.

In Figs. 3 to 7 inclusive reference letters are used to identify the various harnesses 17, the various supporting bands 18 and the various cables 21 connecting the harnesses to the rollers 20. In Fi 4 the harnesses 17 and 17, the harnesses 1 and 17 d and the harnesses 17 and 17 are supported respectively by the bands 18, 18" and 18, each band having one end connected to one harnesses of the corresponding pair. The harnesses 17, 17 and 17 are connected by cables 21 with one roller 20 and the harnesses 17", 17 and 17' are connected by cables 21 with the other roller. Thus when one roller 20 is actuated the harnesses 17, 17 and 17 are pulled downwardly as shown in the left hand section of Fig. 4 and the bands 18, 18 and 18 pull the remaining harnesses upwardly. When the other roller 20 is actuated the positions of the harnesses are just reversed as shown in the right-hand section of Fig. 4. The wire cloth produced with this arrangement of harnesses has the ordinary weave or one over and one under as shown in the first illustration of Fig. 8.

To produce the second illustrated Weave in Fi g. 8, the harnesses are connected to-the supporting bands 18 and the rollers 20 are disclosed in Fig. 5. Harnesses 17 and 17 are connected by band 18. Harnesses 17 and 17 are connected by supporting band 18". The harness 17 is connected to the harness 17 by the band 18. Harness 17 is connected by the bands 18 and 18 with the harnesses 17 and 17 respectively. The harness 17 is connected by the band 18 with the harness 17. The harnesses 17 and 17, the harnesses 17 and 17, the harnesses 17 and 17 are connected by the cables 21, 21" and 21 respectively with the rollers 20. The various positions assumed by the harnesses are disclosed in the three sections of Fig. 5. The first position in this figure shows the harnesses 17 and 17 pulled down due to actuation of the corresponding roller 20 by its actuating lever 22. The remaining levers 22 have been operated by their cams, thus permitting the harnesses 17", 17, 17 and 17 f to be raised to the position shown. In the second position, the harnesses 17 b and 17 are pulled down, the harnesses 17 and 17 have remained up, and the harnesses 17 and 17 have been lifted. In the third position, the harnesses 17 and 17 are pulled down, the harnesses 17 and 17 remain up, and the harnesses 17 and 17 are raised. 'From this position, the harnesses are returned to the first position.

To produce the third weave illustrated in Fig. 8, the harnesses are connected as shown in Fig. 6. The harness 17 is connected to the harnesses 17 and 17 by the supporting bands 18 and 18 The harness 17 is connected to the harness 17 by the supporting band 18. The harness 17 is connected to the harnesses 17 and 17 by the supporting bands 18 and 18 respectively. The harness 17 is connected to the harness 17 by the supporting band 18. The harnesses 17 and 17, the harnesses 17 and 17, and the harnesses 17 and 17 are connected respectively by the cables 21, 21 and 21 to the rollers 20. In the. first position, the harnesses 17 and 17 are-down and the harnesses 17", 17, 17 and 17 Y are up. In the second position, the harnesses 17 and 17 are pulled down, the harnesses 17 and 17 remain up, and the harnesses 17 and 17 are raised. In the third position, the harnesses 17 and 17 are pulled down, the harnesses 17 and 17 remain up, and the harnesses 17 and 17 are raised. From the third position, the harnesses are returned to the first position.

To produce the fourth weave illustrated in Fig. 8, the harnesses are connected as shown in Fig. 7. The harness 17- is connected by supporting bands 18 and 18 with the harncsses 17 and 17 b respectively. The harness 17" is connected by supporting band 18 with the harness 17. The harness 17 is connected by the supporting bands 18 and 18 with the harnesses 17 and 17 e respectively. The bar ness 17 'is connected with the harness 17 i by the supporting band 18. The harnesses 17" and 17 the harnesses 17 and 17, and the harnesses 17 and 1 7 are connected by the cables 21, 21 and 21 respectively with the rollers 20. In the first position, the harnesses 17" and 17 a are down and the harnesses 17 17, 17 and 17 are raised. In the second position, the harnesses 17 b and 17 are pulled down, the harnesses 17 d and 17 remain raised. and the harnesses 17 and 17 are raised. In the third position, the'harnesses 17and 17 t are pulled down, the harnesses 17 and 17 remain up, and the harnesses 17 b and 17 are raised. From the third osition, the harnesses are returned to the first position.

In the arrangement. disclosed in Figs. 5, 6 and 7 the harnessesare serially drawn down in pairs and the remaining harnesses are either moved upwardly or maintained in raised position bymeans of the bands connecting the two depressed harnesses with the remaining harnesses. Each pair'of harnesses is so connected by means of the supporting bands to the remaining harnesses that when any airof harnesses is in the lowered position t e remaining harnesses are in raised position. f

In using the loom above describedto produce without rethreading a wire cloth having the different weaves illustrated in Fig.8, the

machine is threaded inthe usual manner with the warp wire A passing through the harnesses, the lay beam. and around the breast beam 12 to the cloth roller 13. Theharnesses are supported by three bands and one harness of each pair isconnected to one roller 20 and the remaining harnesses to' the other roller 20, as diagrammatically, shown in Fig. 4.

" 180 cams are provided for operating theactuating lever-$22.} :The loom is then operated in the ordinary manner toweave as much cloth as is desired.

When it is desired-tojchange from thefirst to the second weave of'Fig- 8, the 100mm stopped and the connections changed. The

harnesses 17 are then supported by the bands 18 and are connected by the cables 21 to the rollers 20 as diagrammatically disclosed in Fig. 5. The countershaft 26 is replaced by a countershaft equipped with three 240 cams 25. The machine is then again operated in the normal manner. change from the second to the third weave disclosed in Fig. 8, the loom is again stopped. The harnesses 17 are then connected to the bands 18 and by the cables 21 to the rollers 20 as disclosed in Fig. 6. When it is desired to change from the third to the fourth weave disclosed in Fig. 8, the harnesses are connected to the bands 18 and by the cables 21 to the rollers 20 as disclosed in Fi 7.

All the above changes 0? connections and substitutes of cams ma be accomplished without in any way distur ing the warp wires A. These wires remain threaded through the harnesses and through the lay beam regardless of what changes are made in the means for actuating the harnesses. It is therefore possible with this loom to produce a continuous length of cloth having diflerent weaves without removing the cloth from the loom and without rethreading the loom.

It is apparent that the harnesses may be differently connected by the bands 18 and to the rollers 20 by the cables 21 than has been disclosed herein, and that these other connections lie within the spirit of this invention. Although the cams have been disclosed as being 230 of are, it is apparent that they might be 120 of are instead and still accomplish substantially the same results. In such an event, instead of two harnesses being down in each position and four up, there wouldbe two harnesses up and four down ineach position.
